A double skinned feed or scavenge pipe assembly comprises; an inner pipe (22) and an outer pipe (23) enclosing the inner pipe and defining an annular space (24) between the inner pipe and the outer pipe and a sleeve (28) configured to slip over the outer pipe (23). Complementary threads (29) are provided on an outer wall of the outer pipe (23) and an inner wall of the sleeve (28). A lock, for example in the form of a locking nut (31) is positioned over the outer pipe (23) when the complementary threads (29) of the outer pipe and sleeve are engaged. The configuration of the assembly is such that, in use, the sleeve (28) is slidable between a first position where the inner pipe (22) is accessible and a second position wherein the inner pipe (22) is completely enclosed.

A connector for providing a leak resistant flow path between fluid conduits includes a female connector, a male connector, and a tubular fluid conduit that extends through a conduit passage in the male connector and into a conduit receiving passage in the female connector. The connector can include optional anti-cantilever features that provide a more effective axial seal when using a seal washer recessed into a planar surface of the male connector to supplement a radial seal provided by an O-ring sealing member between the tubular fluid conduit and the conduit receiving passage.

A quick connector assembly and a quick connector device are disclosed. The quick connector assembly includes a first base, a first fluid interface assembly and a valve assembly. The valve assembly regulates whether a fluid flows through the quick connector assembly or not, and thereby sealing the flow of the fluid at both sides of the quick connector assembly. The quick connector assembly and the quick connector device in an embodiment of the present disclosure can regulate the flow of the fluid effectively and provide better barriers to keep concurrent flows separated and isolated. Especially, the quick connector device can be used in slurry delivery system which has fluid being abrasive fluid or solid contained liquid.

A single piece structural connector is provided that includes a single machined aluminum piece having first and second circular ends including a plurality of bolt holes and a center hole. The connector also includes an alignment dowel positioned on the center hole. The alignment dowel is configured to tightly fit into a center hole of a pipe plate.

Spacers are provided for maintaining annular tube spacing, particularly at tube ends, in coaxial tubing systems, while also proving fluid passages ways permitting fluid flow between tubes of the coaxial tubing system. The spacers may be made of conductive material for enabling electrical coupling of the inner and outer tubes, and thus grounding of the inner tube. The spacers define a retention groove extending around their periphery for receiving a crimped portion of the outer tube, so as to mechanically fix the spacer in a longitudinal position relative to the coaxial tubing system. Accordingly, the spacer does not rely on “springbuck” characteristics of bent coaxial tubing systems for fixation, and thus is suitable for use in both bend and unbent portions of coaxial tubing systems.

This connection device (D) comprises a shaft (17) which is mobile in translation, a piston (19) integral with the shaft (17), a sleeve (35) which extends around the shaft (17), this sleeve being movable between a rear position and a forward position, and locking members housed in the sleeve (35), each locking member being movable relative to the sleeve between a locking configuration and a release configuration. The shaft (17) is movable between a disconnected position in which the shaft (17) does not oppose movement of the locking members to their release configuration, and the sleeve (35) is in the forward position, and a connected position in which the shaft (17) opposes movement of the locking members into their release configuration and the sleeve (35) is in the rear position, through an intermediate position, in which the shaft (17) opposes movement of the locking members into their release configuration and the sleeve (35) is in the forward position.

A method of connecting a pipe to a cast fitting, the method can include casting a body including a first body end and a second body end disposed opposite from the first body end, wherein the body defines an axis extending from the first body end to the second body end, wherein the body includes a first neck disposed proximate to the first body end wherein the body further includes an inner body surface defining a bore extending through the body from the first body end to the second body end, and wherein the body further includes an outer body surface spaced from the inner body surface a predetermined wall thickness.

A connector which couples to an outlet conduit to decrease an outlet conduit passageway pressure differential between outlet conduit opposing first and second ends, whereby the connector includes a mixing chamber having a first inlet port in fluidic communication with a connector first open end and the mixing chamber; an outlet port in fluidic communication with the mixing chamber and a connector second open end; and a second inlet port in fluidic communication with the connector second open end and the mixing chamber. Additionally, a connector including a connector internal surface defining a connector passageway which communicates between connector first and second open ends; and a sensor module operatively coupled to the connector passageway to sense a parameter of a first fluid flowing in a first fluid flow path through the connector passageway.
